Suppose buyers of vodka are required to send $5.00 to the govt. for every bottle they buy. Further, suppose this tax causes the effective price received by sellers of vodka to fall by $3.00 per bottle.
-This tax caused the demand curve for vodka to shift downward by $5.00 at each quantity of vodka -the price paid by buyers is $2.00 per bottle more than it was before the tax -sixty percent of the burden of the tax falls on sellers
Refer to Figure 6-2. The price ceiling
-is binding. -causes a shortage. -causes the quantity demanded to exceed the quantity supplied. All of the above are correct.
suppose sellers, rather than buyers, were required to pay this tax (graph). Relative to the tax on buyers, the tax on sellers would result in
-the same amount of tax revenue for the govt. -buyers bearing the same share of the tax burden -sellers bearing the same share of the tax burden -the same amount of tax revenue for the govt.
Refer to Figure 6-5. Suppose the market is initially in equilibrium. Then the government imposes a price control, as represented by the horizontal line on the graph. If the price control is a price floor, then the price control

1.60, and supply is elastic.
If the price elasticity of demand for aluminum foil is 1.45, then a 2.4% decrease in the price of aluminum foil will increase the quantity demanded of aluminum foil by
3.48%, and aluminum foil sellers' total revenue will increase as a result.

Refer to Figure 6-22. Suppose the same supply and demand curves apply, and a tax of the same amount per unit as shown here is imposed. Now, however, the buyers of the good, rather than the sellers, are required to pay the tax to the government. After the buyers pay the tax, relative to the case depicted in the figure, the burden on buyers will be
the same, and the burden on sellers will be the same.
Refer to Figure 6-25. Suppose the same supply and demand curves apply, and a tax of the same amount per unit as shown here is imposed. Now, however, the sellers of the good, rather than the buyers, are required to pay the tax to the government. After the sellers are required to pay the tax, relative to the case depicted in the graph, the burden on buyers will be
the same, and the burden on sellers will be the same.
To say that a price ceiling is binding is to say that the price ceiling is?
-results in a shortage - is set below the equilibrium price -causes quantity demanded to exceed quantity supplied
If a 20% change in price results in a 15% change in quantity supplied, then the price elasticity of supply is about
0.75, and supply is inelastic.
Suppose the price of a bag of tortilla chips decreases from $3.00 to $2.50 and, as a result, the quantity of tortilla chips demanded increases from 200 bags to 300 bags. Using the midpoint method, the price elasticity of demand for tortilla chips in the given price range is

demand curve for pants to shift down by $5.
Inelastic
demand is said to be inelastic if the quantity demanded responds only slightly to changes in the price.
Holding all other forces constant, if decreasing the price of a good leads to an increase in total revenue, then the demand for the good must be
elastic

increase, and the quantity sold in the market will increase.
Holding all other forces constant, if increasing the price of a good leads to an increase in total revenue, then the demand for the good must be
